Thread Subject:

importing AutoCAD DXF or DWG

Hi all,

Does anyone know how to import (plot) AutoCad DXF or DWG files in Matlab?

At the moment I'm using a workaround: converting the DXF using the
external program dxf2xyz 2.0 to an ASCII file with x,y,z values
(manually, that is).

The quality of the plots this produces is not too great (there are some
conversion errors). Also, since I'd like to be able to import DXF files
from a GUI, the external workaround is not good enough.

Does anybody know of a way to import DXF of DWG into Matlab?

Thank you,

Jos

Let me know where to send you some (partial) solution.

Have you actually managed to parse the AutoCad DWG or DFX format and
import it into Matlab?
Well, that's most impressive! I would be very interested in it also..
do you parse lines,curves etc. or just points?
it you actually import all entities then many many kudos to you!!
why don't you just post a snippet here or put it in file exchange so
we can all enjoy?
thanks
Miltiades

Just use this e-mail address (without everything between %%) or the
e-mail address I directly e-mailed you from.

Thank you!

Hi Jos,
I tried to send you an email asking for a copy of your dxf reading
functions but it was refused saying "Domain not found".
Can I have a copy of it as well?

Thanks

It would ba fantastic if this code could be send to Matlab Central.

Hello....
Can anybody send me a copy of this code?
I need to do this and also manipulate the file from matlab, and im
learning matlab at the moment...

Dear Miltiades Salvanos,

Please do also help me read the Dxf format.

Regards
Manoj

I have not sent the code to matlab central because it is not good
enough according to my standards. It deals only with isolated points,
LINE, POLYLINE and ARC (using the DXF notation). We did not attempt
to parse ELLIPSE, SPLINE, etc. but I guess it could be done. If you
read in the web about DXF you will soon find that many people blame
AutoDESK for the poor design and implementation of DXF. So, making
reliable code to read it into matlab is pervaded by the same virus:
you might read without problems DXF for ACAD R12, but not DXF for
ACAD R14 neither ACAD 2000.
I will be happy to share the present code with anyone which wants to
have it.
It will be a good idea to consider the new DWF format; unlike DWG and
DXF, AutoDESK provides source code in C to read and write it, so
(hopefully) anyone more or less proficient with C could serve the
matlab community creating a mex file once for all.
Regards
Carlos
PD: Hope that my e-mail will not be too difficult to decipher!

Hi,
I'm also very interested in having a look at this code. I understand
your concern ACAD and also the new opportunity we may have with DWF
source codes.
Anyway, thanks in advance

Hi all,
Is there a way to import a 2d drawing to matlab then? I ve seen quite some discussion but not sure what I need to do. Any advice is welcome
Thanks

Hi Carlos!!! I'm also interested in the code that imports DXF files into MATLAB!!!it would be great if you could send it to me!!

Thx

Camilo Diaz

Hi Carlos,
    May I have a look at that piece of code you had written. I'd also be grateful to let me know of any helpful material regarding .dwg extension that you wrote your code based on that.
Best Regards,
Hamid.

i need to convert only lines and points ...... it will be great if we share this code ??

Dear Carlos,

I would be also very glad to receive your code in spite of the described drawbacks.

Thank you in advance
